To all whom it may concern:

Beit known that I, BENJAMIN HOLT, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented new and useful Improvements in lilauling-'lrucka of which the following is a specification.

My invention relates to a truckwhich is especially designed for hauling heavy loads such as lumber, ore in buckets, and the likeupon ordinary roads or surfaces.

It consists in a combination frame, wheels upon which said frame is mounted, and details of construction which will be .more fully explained by reference `to the accompanying drawings, in which- Figure 1 is a erspective view of my improved truck. 1ig. 2 is 'a vertical sectional view of the steering-wheel and frame, and Fig. 3 is a perspective view of the brake mechanism.

It is the object of my invention to provide a powerful truck ada ted to convey very heavy loads over roads or rough irregular surfaces.

The frame is composed of main parallel I- beams A and exterior beams A. Transversely across the beams A A extend the heavy timbers 2, to which the beams are securely fastened. The space between the beams AA serves to contain the main bearing-wheels 3. The shafts of these wheels extend across the spaces and are journaled to turn in boxes upon the beams A A', as shown at 4. These boxes may satisfactorily be of the same class and nature as railway-car axle-boxes; The axles 5 .may have collars, as

at 6, shrunk upon their outer ends and abutting against t e ends of the journal-boxes. The I-beams A A are here shown as having their rear ends substantially even transversely. The front ends of the beams A extend considerably forward of the beams A', and these front ends are united by diagonal beams 7, firmly bolted. to the beams. Between the front ends of the beams A is the single bearing and steering-Wheel 8. All of these wheels are here shown as made with broad metal rims. A hub 9, having flanges, as shown at 10, through which the spokes 11 of the wheel have their inner ends passed, and the outer ends having beveled heads, fit corresponding holes in the rims. By means of nuts, as at 12, turnable upon the screwthreaded inner ends of the s okes and Within the flanges 10, tension maylhe brought upon these spokes. The spokes are inclined alternately from the flanges 10 upon each side of a vcenter line, and thus give suilicient transverse rigidity to the wheel. The shaft of the front Wheel is turnable in boxes, as at 4, all the journals being of the railWay-car-axle pattern, as here shown.

13 is a yoke fitting over the wheel S and having a central king-bolt 14 passing up through the timber 15, which timber extends transversely above this wheel and is bolted through to the front ends of the beams A,

. whichextend to a point opposite the center of the wheel. Between these beams is supported a ring 16 and within this ring is fitted the turnable ring or fifth-wheel 17, which carries the journal-boxes and frame of the front wheel 8. This ring 17 has a number of wheels or rollers, as at 18, turning on vertical axes, with their peripheri es in contact with the ring 16, so that by suitable connections the front wheel may be turned to steer the vehicle, the ring 17 turning freely within the ring 16. Bars 19 extend across the ring 17 contiguous to and parallel with the sides of the wheel 8 and extending forwardly have eyes or journals through which passes a pivot-bolt 20. U on this bolt is mounted the yoke 21, by w ich the means for hauling the car or truck may be made. In the present case I have shown a draw-bar 22 slidable through a sleeve 23, formed upon the front of the yoke or clevis 21, and at the rear end this draw-bar is surrounded by a spring, as at 24, of sufficient stiffness to allow a certain amount of elasticity in starting the load.

The yoke 21 may be held up and prevented from dropping by means of links with an elastic spring 25, which links are connected with a post 26, from which the yoke is normally suspended, so that its front end and the draw-bar are substantially in line to be connected with the motor or with the leading car Where the cars are to be connected in' train. The spring and the suspending links allow-of Asuch vertical motion of the yoke as may be necessary to conform to irregularities of the surface over which the connected cars may be passing. y

In order to connect a series of these cars in a train which may be hauled by traction-engine or other power, I have shown the clevis or attachment at 28, which is bolted or other- Wise secured between the rear ends of the brace-bars 27. These brace-bars diverge from the clevis, passing into the space be- IOO IIO

- 1o tween them for any short turn that it may be desired to make.

Upon the transverse timbers 2 are fixed channel-irons 28, and these channel-irons serve as tracks within which the bars 29 are r slidable either with or without antifrictional bearing rollers or surfaces. At the ends of these bars 29 are the loops or eyes 30. For the hauling of lumber it is piled upon the bars 29 and to any desired height and is then sezo cured in place by chains passing over the lumber and securely fastened to the attachments 30 at each end of the transverse timbers and so secured that the load cannot shift While being transported.

25 Cars of this description may be coupled as described, so as to forml trains of several cars, which are usually hauled by a traction-engine running over the ordinary surface of the ground, and by the peculiar arrangement of 3o the connections the train is exceedingly flexible in its movements. It will be understood that cars thus constructed are capable of trans orting any class of material ormerchan ise required.

' 3 5 In order to regulate the speed and to hold the cars-on downgrades, I have shown brakes which consist of straps 31, passing over the peripheries of the wheels, having one end pivote to the timbers; or suitable support and the other end connected with a train of levers, as at 32, having connecting-rods 33 extending from each of the levers 32 to a handlever 34, by the operation of which the brakes fdr ioth Wheels Lwill be simultaneously opera e To prevent the load from sliding off bodily when passing over uneven surfaces, I have shown stop-blocks 35, adapted to fit in the channel-guides 2,8 at the ends of the bars 29. These stops have holes made transversely through them to receive bolts 36, which also, passing through the channel-irons, hold the 4blocks in place. By withdrawing the bolts and removing the stops'at the side toward 5 5 which the load is to be discharged the bars 29, With their load, may be hauled off by attaching haul-ropes to the outer parts of the loops 30 and placing skids lto receive the wei ht of the load When removed.
